导出Excel时，通过自定义Attribute设置表头

var shipmentColumnNames = new List<string>();
var shipmentColumnNames = new List<string>();
var shipmentPropNames = new List<string>();
var props = typeof(TestClass).GetProperties().ToList();
props.ForEach((p) => {
     if (p.IsDefined(typeof(ExcelColumnNameAttribute), false))
     {
           ExcelColumnNameAttribute x = (ExcelColumnNameAttribute)p.GetCustomAttribute(typeof(ExcelColumnNameAttribute));
           shipmentColumnNames.Add(x?.ColumnName ?? p.Name);
           shipmentPropNames.Add(p.Name);
     }
     else
     {
          shipmentColumnNames.Add(p.Name);
          shipmentPropNames.Add(p.Name);
     }
});

public class ExcelColumnNameAttribute:Attribute
{
     public string ColumnName { get; set; }
}
